Worksite characteristics and changes in worksite tobacco-control initiatives. Results from the COMMIT study

Worksite tobacco prevention in the Canton of Zurich: stages of change, predictors, and outcomes

OBJECTIVES

This study provides information about the prevalence of tobacco prevention (TP) and the stages of change with respect to the introduction of TP among companies in the Canton of Zurich (n = 1,648). It explores the factors that predict restrictiveness of smoking policies, number of individual support measures, interest in services to promote TP, and the relationship between TP and health outcomes.

METHODS

Data were gathered by means of a written questionnaire and analysed using ordinal regression models.

RESULTS

Whereas many companies maintain smoke-free policies, only few provide cessation-courses. Health and welfare organisations have strictest, and building and hospitality companies have least strict policies. Company size predicts number of individual support measures but not policy restrictiveness. Both measures are predicted by personal concern of the representative. Interest in services is predicted by tobacco-related problems and medium stages of change. Finally, stricter policies are associated with lower proportion of smokers and less tobacco-related problems.

CONCLUSIONS

Health professionals should support less advanced companies in their endeavour to implement TP. The findings provide a baseline to evaluate the implementation of the forthcoming smoke-free legislation.

Correlates of persistent smoking in bars subject to smokefree workplace policy

This study's goal was to characterize physical and social environments of stand-alone bars associated with indoor smoking despite California's smokefree workplace law. In a random sample of 121 stand-alone bars in San Francisco, trained observers collected data on patrons, staff, neighborhood, indoor settings and smoking behaviors. Using bivariate (chi-square) and hierarchical linear modeling analyses, we identified four correlates of patrons' indoor smoking: 1) bars serving predominantly Asian or Irish patrons, 2) ashtrays, 3) bartender smoking, and 4) female bartenders. Public health officials charged with enforcement of smokefree bar policies may need to attend to social practices within bars, and heighten perceptions of consistent enforcement of smokefree workplace laws.

Educational attainment and cigarette smoking: a causal association?

BACKGROUND

Despite abundant evidence that lower education is associated with a higher risk of smoking, whether the association is causal has not been convincingly established.

METHODS

We investigated the association between education and lifetime smoking patterns in a birth cohort established in 1959 and followed through adulthood (n = 1311). We controlled for a wide range of potential confounders that were measured prior to school entry, and also estimated sibling fixed effects models to control for unmeasured familial vulnerability to smoking.

RESULTS

In the full sample of participants, regression analyses adjusting for multiple childhood factors (including socioeconomic status, IQ, behavioural problems, and medical conditions) indicated that the number of pack-years smoked was higher among individuals with less than high school education [rate ratio (RR) = 1.58, confidence interval (CI) = 1.31, 1.91]. However, in the sibling fixed effects analysis the RR was 1.23 (CI = 0.80, 1.93). Similarly, adjusted models estimated in the full sample showed that individuals with less than high school education had fewer short-term (RR = 0.40; CI = 0.23, 0.69) and long-term (RR = 0.59; CI = 0.42, 0.83) quit attempts, and were less likely to quit smoking (odds ratio = 0.34; CI = 0.19, 0.62). The effects of education on quitting smoking were attenuated in the sibling fixed effects models that controlled for familial vulnerability to smoking.

CONCLUSIONS

A substantial portion of the education differential in smoking that has been repeatedly observed is attributable to factors shared by siblings that contribute to shortened educational careers and to lifetime smoking trajectories. Reducing disparities in cigarette smoking, including educational disparities, may therefore require approaches that focus on factors early in life that influence smoking risk over the adult life span.

Availability of smoking prevention and cessation services for childhood cancer survivors

OBJECTIVE

To characterize the smoking-related services available to childhood cancer survivors and describe organizational characteristics that were related to institutions' capacity to provide smoking services.

METHODS

Institutions affiliated with the Children's Oncology Group were surveyed from 2003 to 2004.

RESULTS

Of the 132 responding institutions, 85% assessed the smoking status of their cancer survivors intermittingly, but only 3% assessed smoking status at every visit, as recommended by the PHS guidelines. A minority of sites offered either smoking prevention (39%) or cessation (25%) services; 58% of sites had a mechanism in place to refer survivors for cessation services. In multivariate analyses, the most parsimonious model predicting capacity for smoking service delivery included barriers, respondents' attitudes, complexity, and institutional stability.

CONCLUSIONS

These data highlight an important need to improve the availability of smoking services for childhood cancer survivors. Additionally, these findings will inform the development of future interventions that are sensitive to barriers and facilitators to providing prevention services.

A "smoke-free" hospital in Israel--a possible mission

BACKGROUND

A revised antismoking law in Israel (August 2001) called for a complete ban of smoking in hospitals. An evaluation of a hospital process and short-term outcome of implementing such policy may guideline its sustainability.

METHODS

Two cross-sectional, random-sample surveys of employees 3 months before policy implementation, and 6-9 months post-implementation. The pre-implementation survey included 368 employees (90.4% response rate) and the post-implementation survey, 364 (92.8% response rate).

RESULTS

The 'smoke-free' policy significantly reduced smoking in the unauthorized areas. Before implementation, 63% of staff reported frequently observing smoking in the hospital, compared to 40% 6 months post-policy implementation (P < 0.001). Significantly more smokers reported leaving their workplace to smoke (17% pre- vs. 62% post-implementation, P < 0.0001). Sixty-five percent of smokers, in both surveys, agreed that "a smoke-free policy is unfair to smokers". Fewer nonsmokers subscribed to this belief: 42% pre- and 34% post-implementation. Smoker prevalence remained unchanged (19%).

CONCLUSIONS

Implementation of a "smoke-free" policy is an effective way to reduce smoking in the hospital environment. More effort is required, however, to help staff quit smoking altogether.

Community interventions for reducing smoking among adults

BACKGROUND

Since smoking behaviour is determined by social context, the best way to reduce the prevalence of smoking may be to use community-wide programmes which use multiple channels to provide reinforcement, support and norms for not smoking.

OBJECTIVES

To assess the effectiveness of community interventions for reducing the prevalence of smoking.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group specialised register, MEDLINE (1966-August 2001) and EMBASE (1980-August 2001) and reference lists of articles.

SELECTION CRITERIA

Controlled trials of community interventions for reducing smoking prevalence in adult smokers. The primary outcome was smoking behaviour.

DATA COLLECTION AND ANALYSIS

Data were extracted by one person and checked by a second.

MAIN RESULTS

Thirty two studies were included, of which seventeen included only one intervention and one comparison community. Only four studies used random assignment of communities to either the intervention or comparison group. The population size of the communities ranged from a few thousand to over 100,000 people. Change in smoking prevalence was measured using cross-sectional follow-up data in 27 studies. The estimated net decline ranged from -1.0% to 3.0% for men and women combined (10 studies). For women, the decline ranged from -0.2% to + 3.5% per year (n=11), and for men the decline ranged from -0.4% to +1.6% per year (n=12). Cigarette consumption and quit rates were only reported in a small number of studies. The two most rigorous studies showed limited evidence of an effect on prevalence. In the US COMMIT study there was no differential decline in prevalence between intervention and control communities, and there was no significant difference in the quit rates of heavier smokers who were the target intervention group. In the Australian CART study there was a significantly greater quit rate for men but not women.

REVIEWER'S CONCLUSIONS

The failure of the largest and best conducted studies to detect an effect on prevalence of smoking is disappointing. A community approach will remain an important part of health promotion activities, but designers of future programmes will need to take account of this limited effect in determining the scale of projects and the resources devoted to them.

Using theory to understand the multiple determinants of low participation in worksite health promotion programs

Low participation at the employee or worksite level limits the potential public health impact of worksite-based interventions. Ecological models suggest that multiple levels of influence operate to determine participation patterns in worksite health promotion programs. Most investigations into the determinants of low participation study the intrapersonal, interpersonal, and institutional influences on employee participation. Community- and policy-level influences have not received attention, nor has consideration been given to worksite-level participation issues. The purpose of this article is to discuss one macrosocial theoretical perspective--political economy of health--that may guide practitioners and researchers interested in addressing the community- and policy-level determinants of participation in worksite health promotion programs. The authors argue that using theory to investigate the full spectrum of determinants offers a more complete range of intervention and research options for maximizing employee and worksite levels of participation.

Workplace tobacco policy: progress on a winding road

This is a report of a pre- and post-intervention telephone survey to track changes in workplace tobacco policy in Pima County, Arizona, from 1997 to 1999. During this period, an extensive effort was made to assist workplaces to establish and enforce formal tobacco use policies. A random sample of 1134 workplaces, stratified by workforce size, was surveyed in 1997. Complete interviews were conducted with 934 (82.4%) workplaces. All 934 workplaces were contacted for the follow-up survey that was conducted in 1999. Of these, 824 (88.2%) completed follow-up surveys. The analyses presented were conducted on businesses that were included in both the baseline and follow-up surveys, and that reported having at least one employee on-site (n = 813). Tobacco policies and smoke-free policies were more likely to be found in larger businesses and businesses with a predominantly female workforce. There was no clear policy progression from having no policy, to having a policy, to becoming smoke-free. There was a small but significant overall decrease (4.8%) in the proportion of businesses having policies in the last two years. We found that 10.3% (75) of businesses that had policies in 1997 had dropped their policies by 1999, and that 13.4% (73) of worksites that were smoke-free in 1997 retained tobacco policies but were not smoke-free in 1999. However, formalization of policy in writing and the number of enforcement strategies utilized increased. These findings suggest that efforts to encourage businesses to establish workplace tobacco policies must be sustained even after policies have been established.

The relationship between organizational characteristics and the adoption of workplace smoking policies

Organizational-level variables that are hypothesized to influence the level of smoking policy restrictions and the prevalence of smoking control activities were tested in a sample of 1 14 worksites that participated in the Working Well Trial, a national trial of worksite health promotion. Predictors related to more restrictive policies included smaller size, larger percentage of white-collar workers, larger number of complaints about environmental tobacco smoke, less complexity, more formalization, and having a CEO who valued health and employees' well-being. The number of smoking control activities offered in a worksite was predicted by having a larger blue-collar workforce, a higher percentage of female employees, higher levels of workforce stability, and a CEO who valued health and employees' well-being. Efforts to identify predictors of companies' adoption and implementation of workplace-based policies and interventions are an important part of tobacco control efforts and will enhance future intervention and research efforts.

Measuring worksite resources for employee heart health

PURPOSE

Intervention at the organizational rather than the individual level is gaining greater attention in worksite health promotion efforts. However, little research has been done on instruments to measure this domain. Therefore, the purpose of this study was to further test the utility of an existing organizational heart health support instrument by examining relationships among worksite structural characteristics and comparing these results to other survey findings.

DESIGN

One-time cross-sectional.

SETTING

New York State.

SUBJECTS

One hundred fifteen volunteer worksites in the New York State Healthy Heart Program, representing manufacturing, government, education, health care, and other industries.

MEASURES

A survey was conducted using HeartCheck, an organizational assessment of employee support for heart health. HeartCheck contains 175 items measuring organizational support for tobacco control, nutrition, physical activity, stress, screening, and administrative support structure.

RESULTS

On average, only 22% of all worksite resources assessed were present in the sample. Having a workforce greater than 250 provided a 12% increase in predicted overall worksite resources. A predominantly female workforce (> 75%) provided 10% higher levels of worksite stress resources. Worksites with unions had higher levels of resources for physical activity (10%), screening (13%), and general supportive structures (10%). The presence of manual labor diminished support for tobacco control resources (-13%). Finally, manufacturing worksites demonstrated a clear advantage for all types of worksite resources, except for stress.

CONCLUSION

A number of trends found in this study are consistent with earlier work. Industry type and size both predict worksite supports similar to previous studies. Other findings that appear to contradict previous work, including the relatively low level of support observed in this sample, can be explained by the comprehensive nature of the instrument. Overall, these findings demonstrate the utility of HeartCheck.

Take Heart II: replication of a worksite health promotion trial

The purpose of this study was to evaluate the effects of a revised worksite health promotion program that featured an employee steering committee/menu approach to intervention. The "Take Heart II" program was evaluated using a quasi-experimental matched-pair design with worksite as the unit of analysis. Experimental and control worksites did not differ on baseline organizational or employee demographic variables or on baseline levels of dependent variables. Outcome and process results revealed consistent, but modest effects favoring intervention worksites on most measures. Cross-sectional analyses generally failed to produce statistically significant intervention effects, but cohort analyses revealed significant beneficial effects of the Take Heart II intervention on eating patterns, behavior change attempts, and perceived social support. Neither analysis detected a beneficial effect of intervention on cholesterol levels.
